# Promotion condition for ensuring an order contains a minimum quantity of
# applicable items.
#
# This promotion condition is only compatible with the "all" match policy. It
# doesn't make a lot of sense to use it without that policy as it reduces
# it to a simple quantity check across the entire order which would be
# better served by an item total condition.

# Will look at all of the "applicable" line items in the order and
# determine if the sum of their quantity is greater than the minimum.
#
# "Applicable" items are ones that pass all eligibility checks of applicable conditions.
#
# When false is returned, the reason will be included in the
# `eligibility_errors` object.

# @return [Boolean] true if promotion is eligible, false otherwise
